I'm not sure how to use it, so I only confirmed that it powers on. I'm selling it as-is, and returns are not accepted. Includes a carrying bag (the bag is dirty), instruction manual, and charging cable. The D16 features multi-track recording and an LCD display. - Model: D16 - Color: Blue - Input Terminals: XLR, TRS, RCA - Output Terminals: XLR, TRS, RCA - Controls: Faders, Buttons, Knobs - Display: LCD Display - Features: Multi-track recording - Power: AC adapter Thank you for looking.
